           Summary: gst-python: bindings for gst_pad_set_getrange_function
                    missing
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Mac OS
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-python

gst.Pad has bindings for gst_pad_set_chain_function, but not
gst_pad_set_getrange_function.  As a result, it is not possible to create
N-to-1 pad, pull mode, elements in Python.

I took a stab at adding getrange support to gst.Pad by copying and modifying
the bindings for gst_pad_set_chain_function, but because the getrange callback
take a GstBuffer** in which to return the newly created buffer, the bindings
for GstBaseSrc->create are probably a better starting point.
